To all whom t may conce/m:

Be it known that we, VILLIAM G. HAW- Kms, Vivien C. BLooDeooD, andJAMEs lFA.

DONNELLAN, citizens of the United States,

and residents, respectively, ofthe villageof Harvey, the villageof Harvey, and the vcity of Chicago, in the county of Cook and State or' Illinois, havev invented certain new and useful Improvements in anArmoredPneu-- matic Wheel; and we do hereby declare that the following is a full, clear, and exactl description of the same, reference being had to the accompanying drawings, and tothe numerals of reference marked thereon, which form a part of this specification. f f

This invention r lates'more particularly to an improved type of van armored pneumatic wheel whereinian outer solid tire rim is adapted to interlock withand rest on i'ollers oi an inner` pneumatic rim and" to be rotated by said inner rim.'

It is an object of this invention to pro-` vide a wheel having a pneumatic inner rim,-

carrying roller mechanisms for supporting a solid tire outer rim which is spring cushioned. and adapted to be driven: by said in-` roller and spring mechanisms.l y

A further object lof the invention Vis y'to provide a wheel wherein roller mechanisms are mounted on a'pneuinatic inner tireforj' the purpose of adjustably supporting ak solid outer tread tire in position to loe driven by the inner tire throughv spring members.

It is furthermore an object of thisl invention to provide a vehicle wheel wherein a 40 pneumatic inner'tube is separated from an outer solid tire rim section by rollers and springs to permit relative movement between"I the inner tube and said outer rimsection.

It is an important object of this invention to provide a' vehicle wheel having spring controlled rims, separated by roller mech-n anisms to permita slight relative movement of said rims with respect .to one another when the wheel is rotated. o i

Other and further importantobjects ofthis invention-will be apparent fromthe disclosures in the specification and drawings.

The invention (in a preferred vform) is illustrated in the drawings andhereinafter` more ullydescribed.'

WiththeQarniored pncuniaticwheel asf llO nd 1 together nally between the felloe and the wheel disk section. To eliminate 'rictional action between the telloe and the inner rim, the rollers 26, are provided to act as roller bearings. The springs 32, positioned between the spacers 29, and the shoes 23, permit a slight relative movement longitudinally between the wheel disk section and the pneumatic inner rim section.

The inner pneumatic rim section acts to receive and absorb thel shocks transmitted b-y the solid outer tire 40. As shown in Figure 4J the projection 21, seating in the pocket 11, of the rim 10, serves to prevent creeping of the pneumatic tire 17, on the rim 10. Both the pneumatic inner rim section and the outer rim section are resiliently connected with the disk section by means of the springs 32 and 38 respectively. The outer rim rests on the rollers 26, ot the inner rim, and both of said rims are adapted to move radially and longitudinally between the wheel disks 8 and 15.

Figures 7 and 8, disclose amodiiied form of cushioning mechanism connected with the kwheel disk section' and the wheel icelloe. The springs 51, within the telescoping cup members 49-50, are adapted to be compressed to permit a slight relativey movement between the wheel disk section to which the bolt-S48, are secured, and the wheel elloe 48, wherein the telescoping members are disposed to coact with the telloe partition, plates 46, through` which the bolts 47, project. The wheel felloe is driven by the disk section through the medium of the spring cushioned telescoping members '49-50, and the mounting bolts 47 and 48.
